Background - I stumbled upon this answer and it's making me very nervous.
I've only been in the work force for about 1 year, working through a contracting agency (my paychecks are from them) for a different company. On my resume, I thoughtlessly listed the company I actually worked without mention of the contracting agency. It was an honest (and I think not unreasonable) mistake from someone new to the industry and not intentionally meant to mislead, since my interaction with the contracting agency has been so limited.
The references I listed were also all from the company for which I actually performed the work.
I just accepted a job offer from a new company - is the contract nature of my employment worth mentioning to the new company at this point? Would this be grounds for them to rescind my offer, and if so, how best should I address this?
